Application flledMareh'17,1922i Serial No. 544,414.

This invention relates to oil engines, and

more particularly,

to that type of engines in which a restricted passage or throat is employed between the compression chamber and the working portion of the, cylinder.

One object of the present invention is to improve the combustion in engines of this inafter appear.

Embodiments of this trated in the accompa which: t

Figure 1 is a I of the cylinder 0 in accordance with the fragme pe. H p Other ob ects and advantages will hereinvention are illusnying drawing in ntary sectional viewf an oil engine constructed present invention.

Figure 2 is a sectional view taken substantially on the line 2-2 of Figure 1.

Figure?) is a view similar to Figure 1 illustrating the cylinder of an oil engine of somewhat different form.

selected The engines the four oil engines of although the invention to two cycle engines and to engines of the horizontal type. The engine shown in ures 1 and 2 includes one or for illustration are cycle upright type, is equally applicable more cylinders 10 of any standard or approved construction water jacketed in closing a piston 11 of u the usual manner and ensual form. The cylinder head 12 is provided with the usual exhaust and air intake valves 13 and 14. A

water cooled partition 15 is arranged beneath the cylinder-head 12 in such position as to form a chamber the working portion of the cy ated from 16 segre inder and communicating therewith through a restricted throat or passage 17 extends transversely of of substantially flat, elongate dimensions as to. readi valves 13 and 14. The

The chamber 16 linder and is form, of such ly accommodate the partition 15 is prefthe c erablv formed as adpart of a member 18 removably interpose head and cylinder so as cess to the chamber 16.

In this instance, the passage one end of the chamber 16 forced through the passage ranged adjacent so that the air between the cylinder to permit ready ac- 17 is ar- 17 during the compression stroke will travel toward the other end of fuel is injected into the in a direction contra to flow of air therein an the chamber. chamber, preferably the direction of the d preferably imme- Fig-.

bustion occurs, 1 'lent explosion, as in the case of other on Th ated chamber extending transversely said chamber, a restricted passage diately prior to compression dead center. In this instance, a single injection nozzle 19 of the solid injectionor' pump spray type is employed. The nozzle shown is of the type described in the copendin'g application of Otto A. Banner and Jacob Schhnnberger, tiled March 17, 1922., Serial No. 544.427. It will ,be suflicient here to say that this nozzle includes a pair of convergent fuel discharge ducts by which two jetsof fuel spray necessary to employ compression pressures as high as those commonly required In the Diesel engine, in which the fuel is injected by means of highly compressed air. Furthermore, though a prompt doesnot occur as "a viogines operating on the Otto cycle.

It will be noted that in the engine shown in Figure 1 the upper wall of the partition 15 is substantially parallel to the upper wall of the chamber 16 so that the chamber is of substantially uniform end. The shape of this chamber, however, might be varied somewhat from that shown. For instance, as shown in Figure 3, the upper wall of the partition 15 might be inclined downwardly toward the pass'a e 17 to accommodate a downwardly inc ined spray. Various other changes may be made in the embodiments of the invention hereinabove described, without departing from or sacrificing any of the advantages of the invention as defined in the appended claims.

I claim:

1. In an internal combustion engine the combination of a cylinder having an elonthereof, intake and exhaust valves in one wall of through the opposite wall of said chamber at one end thereof, means for cooling the walls of said and complete com-- depth from end to i i chamber, and means at the other end of said chamber for directing a fuel spray extending longitudinally thereof.

2. In an internal combustion engine the combination of a cylinder having a cylinder head, a water cooled partition in said cylinder cooperating with said head to form an elongated chamber, an openin through said partition at onerend of said chamber. and an injection nozzle at the other end of said chamber for directing a fuel spray longitudinally thereof.

3. In an oil engine the combination of a cylinder having an elongated chamber extending transversely thereof, said chamber being rectangular in transverse section,

means for cooling the walls of said chamber, a iiPassage ad acent one end of said chamber e ectmg communication wlth said chamber and cylinder, and an in'ection nozzle at the other end 0t said cham r for producinga substantially flat fuel spray directed longitudinally thereof. 4. In an oil engine the combination of a cylinder having a shallow elongated chamber extendin transversely thereof, said chamber having a substantially flat wall, intake and exhaust valves in said wall, the opposite wall of said chamber having a passage therethrough adjacent one end thereof, means for cooling the walls of said chamber, and an airless fuel injection nozzle at the other end of said chamber for producing a substantially flat fuel spray directed longitudinally thereof.

In witness whereof, I hereunto subscribe my name this 2nd day of March, 1922.
